Simplify constructor recovery
...
This fixes a bug in the list pattern matching code that caused crashes
in the presence of list guards, and simplifies the pattern splitting
algorithm to avoid complexity and allocations. Previously we would place
arguments-to-be-matched of constructors and lists at the front of
specialized rows for exhaustiveness checking, but at the back for
redundancy checking. Now, we always place them at the back - this avoids
needless allocation, and is not any worse, since we can still recover
the non-exhaustive witnesses by looking at the end of a list, instead of
the front.

Make sure self-recursive checks only happen after typechecking
...
Programs like
```
after : ({} -> a), ({} -> b) -> ({} -> b)
fx = after (\{} -> {}) \{} -> if Bool.true then fx {} else {}
```
are legal because they always decay to functions, even if they may not
look like functions syntactically. Rather than using a syntactic check
to check for illegally-recursive functions, we should only perform such
checks after we know the types of values.
